Ansible ssh giving permission denied error - ssh

Question

I am trying to execute an ansible script against a server1.xxx.com, I am getting a permission denied error.
I have created a ssh key using command
ssh-keygen -f t11pkey
and also have added passphrase, copied the key to the server.
ssh-copy-id -i /home/user.name/t11pkey.pub user.name#server1.xxx.com
my ~/.ssh/config
Host server?.xxx.com
User user.name
Port 22
IdentityFile /home/user.name/.ssh/t11pkey.pub
Permission of my keys:
-rw------- 1 user.name Domain Users 1766 Dec 5 10:55 t11pkey
-rw------- 1 user.name Domain Users 412 Dec 5 10:55 t11pkey.pub

Answer 1

IdentityFile parameter in the config file should point to the private key (t11pkey), not the public one (t11pkey.pub).
